Gunn flat out tells the Playlist that the idea of a Planet Hulk movie or a film teaming the Hulk with the Guardians is total BS.

"I can answer that question very easily: it is absolute, 100% bullshit. It feels like a great relief to finally say this after all the dumb stuff on the Internet. There's not going to be a 'Planet Hulk' movie, there was never going to be a 'Planet Hulk' movie, there was never a plan for the Hulk to team up with the Guardians of the Galaxy – I wouldn't want the Hulk to team up with the Guardians of the Galaxy! And it's all a bunch of complete bullshit."

As Cosmic Book News previously reported, Gunn is using the Sakaraans as a replacement for the Badoon.

The reason we picked the Sakaraan is because we don't own Badoon. In the script it originally said Badoon. So you can blame search and replace for changing Badoon to Sakaaran and leading to the whole 'Planet Hulk' conspiracy."
